摘要： A circuit for protecting a load from an overvoltage can be integrated together with the load on the same chip by an MOS transistor manufacture process. This overvoltage protecting circuit is composed of a surge protection circuit, an overvoltage detecting circuit and a switching circuit. The surge protection circuit including two MOS transistors operates so that a surge voltage applied to a power supply receiving terminal is clamped by virtue of the source-drain breakdown voltage of the two MOS transistors, thereby absorbing the surge energy. The overvoltage detecting circuit including two MOS transistors operates so that a DC voltage supplied from the surge protection circuit is monitored with the source-drain voltage of the two MOS transistors taken as a reference voltage, thereby detecting an overvoltage. An overvoltage detection output brings an MOS transistor of the switching circuit into a turned-off condition to protect the load.

摘要： Dynamic quantitative displacement is converted stably and straight into voltage (D.C. output) by using a high speed detection driving frequency without restricting a response of an operational amplifier. When a dynamic quantity detection electrostatic capacitance changes according to a dynamic quantity, electric charges stored in this element and in a reference electrostatic capacitance become unbalanced to produce a difference value, and an output of an operational amplifier changes according to the difference in electric charge quantity. However, the output becomes finally stable when the electric charges in the dynamic quantity detection electrostatic capacitance and in the reference electrostatic capacitance become equal. The output is proportional to a reciprocal of the dynamic quantity detection electrostatic capacitance and it is a D.C. voltage. Further, output without depending on integration feedback capacitance (feedback condenser) CF can be obtained.
摘要翻译：通过使用高速检测驱动频率将动态定量位移稳定地转换成电压（直流输出），而不限制运算放大器的响应。当动态量检测静电电容根据动态量而变化时，存储在该元件中的电荷和参考静电电容变得不均衡以产生差值，并且运算放大器的输出根据电荷量的差异而变化。然而，当动态量检测静电电容和参考静电电容中的电荷变得相等时，输出最终稳定。输出与动态量检测静电电容的倒数成比例，为直流电压。此外，可以获得不依赖积分反馈电容（反馈电容器）CF的输出。

摘要： A master unit sends a start signal to a slave unit. When receiving the start signal from the master unit, the slave unit sends, to the master unit, a synchronization field that is a data train (pulse signal) indicative of a transfer clock with which the slave unit is able to perform transferring and receiving operations. The master unit sends, to the slave unit, command data in accordance with the transfer clock indicated by the synchronization field sent from the slave unit. In response to the command data sent from the master unit, the slave unit sends, to the master unit, response data in accordance with the transfer clock indicated by the synchronization field. Thus, in a communication system employing a serial data transferring apparatus of the present invention, the master unit establishes the synchronization for the data transfer, while the slave unit is free from a burden of establishing the synchronization for the data transfer. A serial data transferring apparatus is realized which can simplify the structure of the slave unit, cut the total cost, and reduce noise.

摘要： In a thermal-type airflow meter that measures an intake airflow rate in an internal combustion engine of an automobile or the like, there has been a problem that pulsation errors caused by external fluctuations under the environment including a large pulsation and reverse flow in the intake valve are difficult to be reduced. In order to solve this problem, the invention provides a flowmeter comprising a detection element that outputs a non-linear signal corresponding to a flow rate, and a regulation means that regulates an output signal of the detection element for controlling. With this construction, the regulation means executes output regulation processing that regulates irregularities of the detection element in the output signal, and inequality linearization processing that regulates an average value of the output signal after the output regulation processing by means of regulating parameters.

摘要： By sealing a diaphragm with less processes and lower cost and reducing deformation due to remaining stress, a stable and highly reliable pressure sensor construction is proposed. The pressure sensor is low in measurement error and small in floating capacitance and leakage current and good in characteristic. As a means to attain the above object, a polycrystalline silicon diaphragm is sealed with a silicon oxide film deposited through a LPCVD method and then completely covered. The diaphragm is placed on a surface of a semiconductor substrate with a nearly constant gap of 0.15 to 1.3 μm, and has difference-in-grade constructions of a deformation reducing means due to remaining stress.
